Lubricating oil

The object of this invention is the production of an oil for general lubricating purposes.

In the past, it was 7 sible' and quite proper to use oils of viscosities for different purposes.

When an oil was to be used in considered entirely posa pump or in a mechanism subjected to or operating ata and satisfaction, I takecare that the v lubricating oil used be'pure and cl'eara'nd "40 low temperature, a light and readily flowing oil was employed tion. I

When an oil was to be employed in a mechanism operating in or under high temperature, a heavier oil was employed, and, even though the heavy oil was-not entirely efficient, due to its non-fluid qualities, and to the fact that a heavy deposit of carbon might result from its use, still, it was be lieved that a portion of the efficiency might be sacrificed to obtain proper lubrication.

The oil which I am about to describe, although of the viscosity found in heavy lubrieating oils, may be employed temperatures. I

I have found that it is desirable to m vide an oil of thisnature for use on airs ips and in other places. where hydro-carbonengines are used, or where changes in the temwith a degree of satisfac- -perature to very great extents may be' expected. r

In compounding my oil, I employ as a base any suitable mineral lubricating oil, such as the commonly termed machinery which is obtained from the distillation crude petroleum.

I obtain a quantity of mineral lubricating oil and for the purpose of highest-'efficiency without foreign matter or sediment.
